I bought this caliper for my medical school cardiovascular system class. I saw the $5.99 price tag and hopped right on it. When I first took it out of the box, it appeared to be rather cheaply made. As I started reading EKG's, I noticed that the caliper did not hold it's measurement very well. It's too loose...a quality that is not acceptable when you are reading EKG's and millimeters matter. I had to keep re-measuring because the caliper kept collapsing on me ever so slightly. I was getting annoyed. I actually figured that this was normal...until I tried a friend's caliper. His was sturdy...mine was not. His actually held the distance...mine did not. I ran right back to Amazon and ordered the same Prestige brand caliper that my buddy had. The new one arrived today, and I will no longer use this ADC one. There is no comparison between the two. My advice...spend the extra $4.00 and go with the Prestige brand. That's what I wish I had done...you will not be disappointed. As the old saying goes, "You get what you pay for."

the description said it is American Diagnostic Caliper but when I received the item, it looked like a cheap version of caliper (no names or anything). im dissapointed because i would have bought the prestige one instead

This is a simple but effective set of EKG calipers, great for residents and fellows alike. The product is well-made and durable. Comes with a small case for safe-keeping. I recommend this for anyone in cardiology or medicine who frequently reads EKGs.

I bought these for a cardiac arrhythmia class and they worked great. They are nice and tight and hold their measurement well. I've been using them at work (RN) on my cardiac strips and love them! Great tool. Great price. Very fast shipping, too!

Thanks again for shipping out the EKG calipers. They arrived in a timely fashion and work great! They hold their position for accurate measurements and I will recommend your company and products to others!

I have lost a few calipers at work, and I find this an inexpensive replacement each time. I does what it is supposed to, the screw that holds in the middle to keep it in place doesn't seem to loosen as some other calipers do.
